摘要
目的: 建立高效液相色谱法分离和测定消炎利胆胶囊中脱水穿心莲内酯。方法: 采用Shim - Pack CLC-ODSC18 柱, 以0-01 mol·L- 1 磷酸二氢钾溶液( 用磷酸调pH 至2-5) - 甲醇- 四氢呋喃(275∶200∶40) 为流动相, 检测波长250 nm 。结果: 脱水穿心莲内酯峰与其他组分峰的分离度为1, 理论塔板数以脱水穿心莲内酯峰计算为4 600; 线性范围0-4 ~2-0 μg, r= 0-999 8 , 平均回收率为98-6 % , RSD= 2-03% 。结论: 本法准确、简便、快速, 适用于该制剂的质量分析检验。
Objective:To develop a HPLC method for the separation and determination of dehydroandrographolide in Xiaoyanlidan capsules.Methods:Dehydroandrographolide was separated on Shim-Pack CLC-ODS C 18 column (5 μm, 150 mm×6 mm) and detected at 250nm, by using 0 01 mol·L -1 K 2 HPO 4-MeOH-THF(275∶200∶40)as mobile phase. Results:The resolution was 1. The number of theoretical plates calculated for dehydroandrographolide peak was 4 600; the standard curve was linear in the concentration range of 0 4~2 0 μg, r=0 999 8 . The average recovery was 99 2%( RSD =2 50%). Conclusion:This method is accurate, rapid, and simple for quantitative analysis of Xiaoyanlidan capsules.
